Speaking in tongues is never called "ecstatic utterances" in the Bible.
You should do some more Bible research on this word ecstatic -------and what it means and where it can be used ---your ignorance is showing here
Greek word for ecstatic
Strong's Concordance
ekstasis:
a displacement (of the mind), i.e.
bewilderment, ecstasy
I say -------which is what happens when you speak in tongues there VARob -----so you obviously don't speak in tongues or you would know that the mind is displaced and the Holy Spirit who dwells in you is speaking the utterance through you ----
-so the Expanded bible is right in using this descriptive word ------
1 Corinthians 14:14
Amplified Bible
For if I pray in a tongue, my spirit prays,
but my mind is unproductive [
because it does not understand what my spirit is praying].

From Google
Why is speaking in tongues so powerful?
Speaking in tongues
stimulates faith and helps us learn how to trust God more fully. For example, faith must be exercised to speak with tongues because the Holy Spirit specifically directs the words we speak. We don't know what the next word will be.
From Got Questions
Glossolalia, a phenomenon sometimes referred to as “ecstatic utterances,” is the uttering of unintelligible, language-like sounds while in a state of ecstasy.
